UMG 507 : DETECTION OF SHORT INTERRUPTION


FUNCTION:
UMG 507 is a universal measuring device acquires and digitizes the rms values of current and voltage in a network by sampling the input signals. Further calculation is done by the Micro Processor. All the measured values will be calculated and aggregated in intervals of 200 ms, containing 10 power line cycles at 50 Hz
Proper detection of short interruptions including fault recording : Recording of 128 cycles (one rms value each cycle), including 64 cycles pretrigger and transient recorder storing the waveform of 5 power line cycles, 2 cycles pretrigger.
The propagation delay of the internal outputs is < 10 ms and of filed-bus connected outputs is < 200ms.


SALIENT FEATURES:
Continuous voltage and current measurement
Detection of short interruptions (10 ms)

256k Memory, 16MB Flash
Period memory
6 digital inputs / digital outputs
Input for temperature sensors like Pt100, Pt200 etc.
Maximum demand program
RS485 / RS232 / Ethernet
Profibus DP V0, Modbus RTU, Modbus TCP, Modbus Gateway

EMBEDDED WEBSERVER / E-MAIL CLIENT:
UMG 507 can be accessed worldwide through an internet browser by setting up IP-Address and access privileges.

The entire configuration menus are available in HTML pages from the internal webserver. User contributed Java applets and ActiveX components can be stored in the flash memory.

A message will be sent if the set limits are exceeded or other events, to the user-defined email addresses. Stored data can be sent by email at set times and can be processed with PSW software. The supported protocols are : HTTP, SMTP, DNS, NTP, Mod/TCP, Modbus over TCP, DHCP, BootP.

INTERNET CONNECTION via ISDN (or) ADSL ROUTER:
The device can be connected to the internet by an external router (e.g. ISDN or ADSL). SMTP provides Plain / Login / Cram-MD5 (latest encryption standards) authentication to send email messages to your mail box.

MEMORY:
RAM (battery backed) 256 kB
16 MB Flash

Mean values with programmable averaging time of 1-9999 sec. can be stored in the memory. Minimum & Maximum values are also stored for each mean value.

ADDITIONAL MEMORY OPTIONS:
Fault logging (rms value and transients)
Data Recorder (speed up to one value in every 200 ms)
HTML pages, Java Applets (in 16MB Flash Memory)

TRANSFORMER SUPERVISION:
The maximum permissible current for Transformer, fuse and motors can be supervised by setting the k-factor.

The manufacturers ratings of the transformers can be monitored by properly setting one or more of the comparators and routings its output to one of the digital outputs. Further, the readings of the external temperature sensor can be used for the supervision of the transformers.

INPUTS / OUTPUTS:
1 input for temperature sensor (supports PT 100/1000, KTY 83 or 84)
1 analogue input 0(4) – 20 mA.
6 digital inputs, configuration selectable as counting input (max. 20 Hz), pulse input for EMAX, nominal value switch, tariff switch and 32 marker.
6 digital outputs, configuration selectable via programmable logic functions.
2 analogue outputs, configuration selectable for measured values, analog EMAX generator control and field-bus controlled.

Can also communicate as a Modbus RTU master with other fieldbus devices, which support RTU Protocol.

INTEGRATED LOGIC:
128 Programmable logic elements provide connections from the inputs and internal functions of the Device (e.g. comparators) to the digital outputs.

Available Operators : AND, NAND, OR, NOR, XOR, XNOR, edge detection (rising and falling)

Available input data : Trigger events 1-9, weekly time controller 1-24, limit comparator 1-16, EMAX Channel 1-16 and field bus input.

INTERFACES:
